So for 8 years I have been using my 1st-generation iPad Mini, which cannot be upgraded past iOS 9, and therefore I have never had the chance to practice using split-screen or slideover mode (or any of the other multitasking innovations that came with iOS 12). But I've just bought a brand-new iPad and am trying to figure out how to make the most of what ought to be a huge productivity boost.
- What I am doing: with one app open, I swipe up from the bottom of the screen, press & hold Notability in my dock, and drag it to the right half of my screen.
- What I expect to happen: Notability should fill half of the screen, and there should be a movable divider between the two open apps.
- What actually happens: Notability opens in "slide over" mode, filling only about 1/3 to 1/4 of the screen; while it can be moved, it can't be resized.
What am I doing wrong? If an app is in slide over mode, how do I get it into split-screen mode?
